Z & Z Feminised Cannabis Seeds by Exotic Seed
Z & Z is a feminised cannabis seed from Exotic Seed that delivers the fruitiest expression of Zkittlez genetics you're likely to find. Rather than crossing Zkittlez with something else entirely, Exotic Seed took two standout phenotypes of the same cultivar — Zkittlez Z3 #5 and Zkittlez Z3 #7 — and crossed them with each other. The result is a strain that doubles down on everything that made Zkittlez famous in the first place: that sticky-sweet tropical fruit aroma, the dense flower production, and a clear-headed effect that doesn't glue you to the sofa. If you've grown Zkittlez before and thought "this is brilliant, but I want more of it," Z & Z is exactly that.
Z & Z Genetics and Growing Profile
Z & Z sits at 60% indica and 40% sativa — enough indica dominance to keep the plant structure compact and manageable, with enough sativa influence to keep the effect lively. Exotic Seed bred this one for robustness. We've seen a lot of Zkittlez crosses that look gorgeous on paper but turn out fussy in the grow room. Z & Z goes the other direction: she's a sturdy, forgiving plant that works well for growers who don't want to babysit every node.
Indoors, flowering wraps up in roughly 8 weeks — that's quick for a strain with this kind of terpene complexity. Outdoors, you're harvesting in early October, which suits most European climates before the autumn rains set in properly. Indoor yields land between 550 and 600g/m², which is genuinely impressive for a plant that finishes this fast. The flowers come out compact and dense, coated in resin.

Aroma, Flavour, and Terpene Profile of Z & Z
This is where Z & Z really earns its name. Crack open a cured bud and you get hit with fresh tropical fruit — not a vague "fruity" note, but something closer to opening a bag of mixed exotic sweets. There's mango in there, berry undertones, and a sugary sweetness that lingers on your fingers after handling the buds. The smoke carries that same profile through to exhale, and the aftertaste genuinely sticks around. We'd put Z & Z up against any fruit-forward strain on the market for sheer intensity of flavour.
If you want to maximise that terpene expression, keep your drying and curing game tight. A slow dry at around 18–20°C with 55–60% humidity for 10–14 days, followed by a proper jar cure, will preserve those volatile terpenes that give Z & Z its character. Rush the dry and you'll lose half of what makes this strain special.
Effects of Z & Z Cannabis
Exotic Seed describes the effect as clear-headed and uplifting, with a layer of physical relaxation underneath. It's not a couch-lock strain — the 40% sativa genetics keep things mentally active. You can smoke this one during the day and still get things done, though the indica side does build over time, so expect some mellow body comfort as the session goes on. Moderation is worth keeping in mind: the flavour is so moreish that it's easy to overdo it before you realise.
Compared to the original Zkittlez, which can lean heavier on the sedative side depending on the phenotype, Z & Z feels more balanced. The breeders clearly selected for that functional, sociable effect alongside the fruit-bomb terpenes. Good strain for an afternoon with mates or a creative session — less suited as a late-night knockout.
Why Z & Z Stands Out From Other Zkittlez Varieties
The cannabis seed market is full of Zkittlez crosses. Zkittlez x Gelato, Zkittlez x OG, Zkittlez x whatever's trending this year. Most of those crosses dilute the original Zkittlez character by blending it with something else. Exotic Seed took the opposite approach: they refined Zkittlez by crossing it with itself — two different phenotypes selected for complementary traits. Pheno #5 brought the flavour intensity; pheno #7 contributed vigour and yield. The offspring combines both.
The honest limitation? Because this is an intra-strain cross rather than a hybrid with a completely different genetic background, you won't see the same kind of hybrid vigour you'd get from, say, a Zkittlez x Gorilla Glue cross. What you do get is consistency. The phenotypic variation between plants should be minimal, so every seed in the pack should produce something close to what Exotic Seed intended. For growers who want predictability alongside that Zkittlez flavour, that's a real advantage.
How to Grow Z & Z Seeds
- Germinate your feminised seeds using the paper towel method or directly in a starter plug. Keep temperatures around 22–25°C and maintain moisture without waterlogging.
- Transplant seedlings into their final containers once the taproot is established — 11-litre pots work well for indoor grows aiming for that 550–600g/m² target.
- Veg for 3–4 weeks under 18/6 lighting. Z & Z doesn't stretch excessively, so you can afford a slightly longer veg period if you want bigger plants without losing control of canopy height.
- Flip to 12/12 to trigger flowering. The 8-week flowering window means you should see trichome development accelerate around week 5–6.
- Support branches during late flower — the dense buds can get heavy enough to bend stems, especially on the lower branches. Bamboo stakes or a SCROG net will prevent snapping.
- Harvest when trichomes show mostly milky-white colouration with a few turning amber. For a more uplifting effect, harvest on the earlier side; for more body relaxation, wait for 20–30% amber.
- Dry slowly at 18–20°C and 55–60% humidity for 10–14 days, then cure in sealed glass jars for at least 2 weeks. The terpene profile rewards patience here.

Z & Z Seeds
We've been stocking Exotic Seed varieties for a while now, and Z & Z is one of their more interesting projects precisely because it's not trying to be something new. It's Zkittlez, refined. The 8-week flowering time is genuinely fast for the quality of flower this plant produces — a lot of strains that claim 8 weeks really mean 9 or 10, but Z & Z tends to stay on schedule.
One thing worth flagging: the compact bud structure means airflow matters. In humid grow rooms, those dense colas can trap moisture and invite mould if you're not running adequate ventilation. Keep your extraction fan running and consider some light defoliation around week 3–4 of flower to open up the canopy. This isn't a Z & Z-specific problem — it's a dense-indica problem — but it's worth mentioning because losing a harvest to botrytis when you're this close to the finish line is genuinely painful.
If you're choosing between Z & Z and a standard Zkittlez from another seed bank, the question is simple: do you want the classic profile or the refined version? Z & Z pushes the fruit flavour further and gives you a more robust plant. For a first Zkittlez grow, we'd lean towards Z & Z — the added vigour makes it more forgiving.
Frequently Asked Questions
Do Z & Z plants need support during flowering?
Yes. The compact, dense buds get heavy enough to bend or snap branches in late flower, especially on lower and side branches. Use bamboo stakes, plant yo-yos, or a SCROG net from around week 4 of flowering onward.
How do you maximise terpene quality on Z & Z?
Slow drying at 18–20°C with 55–60% humidity for 10–14 days, followed by at least a 2-week jar cure. Rushing the dry is the single biggest terpene killer. During the grow, slightly cooler night temperatures in late flower can also boost terpene production.
Is Z & Z suitable for beginner growers?
It's a solid choice for beginners. The plant is robust, finishes in 8 weeks of flowering, and doesn't require advanced training techniques. Just watch humidity levels around those dense buds and keep airflow strong.
What is the difference between Z & Z and regular Zkittlez?
Z & Z is a cross between two Zkittlez phenotypes (Z3 #5 and Z3 #7), selected to intensify the fruit flavour and improve plant vigour. Standard Zkittlez varies more between seed banks. Z & Z is Exotic Seed's refined, more consistent take on the cultivar.
Can Z & Z be grown outdoors in Northern Europe?
Yes — she finishes in early October, which works for most of Western and Northern Europe if autumn weather cooperates. In particularly wet climates, the dense buds can be vulnerable to mould, so keep an eye on forecasts as harvest approaches.
How much does Z & Z yield outdoors?
Exotic Seed lists indoor yields at 550–600g/m². Outdoor yields depend heavily on climate, soil quality, and container size, but healthy plants in good conditions can match or exceed indoor numbers per plant when given space to grow.
What does Z & Z smell like during flowering?
Expect a strong tropical fruit aroma from around week 4 of flowering onward — sweet, candy-like, with mango and berry notes. A carbon filter is strongly recommended if discretion matters, because this strain is not subtle.
